Abstract

Introduction: Obesity in recent years has increased its prevalence nationally and internationally. Low glycemic index diets decrease weight and regulate insulin levels in obese patients.

Objectives: To determine the effect of a low glycemic index diet in obese women with hyperinsulinemia.

Methods: Analytical, comparative and longitudinal study. The sampling was non-probabilistic, of 102 women, 42 patients with a normocaloric diet of 2000 calories and 60 patients with a diet with a low glycemic index of 1300-1500 calories, for 4 months. Body mass index (BMI) was calculated, height and weight were measured with a stadiometer, with a SECA scale, waist circumference values ​​<88cm. Fasting triglycerides <150 mg / dL with Trinder colorimetric reagent kits and basal plasma insulin between 6-27 uIU / ml. The Wilcoxon and t-Student tests were performed to determine the effects of before and after the treatments.

Results: The women ranged in age from 24 to 69 years. In both diets a significant effect of weight loss (Δ-1,20; Δ-5,56), BMI (Δ-0,96; Δ-2,29) and waist circumference (Δ-4,88, Δ-5,03) were obtained (p <0.001). Triglycerides reduced their values ​​(Δ-5,76; Δ-14) but it was not significant in any of the diets and the low glycemic index diet showed a better reduction in insulin (Δ-1.54) (p <0.001).

Conclusions: Both diets reduce anthropometric indicators, the low glycemic index diet had a better effect in reducing plasma insulin levels, and neither diet was effective in reducing triglycerides.
